<![CDATA[Background: In the digital era, football clubs increasingly adopt mobile applications to enhance fan engagement and service delivery. The PERSIS Solo application is a new digital innovation that provides official club information, ticket sales, and merchandise services. However, there has been no prior evaluation of user acceptance, which is crucial for ensuring the successful adoption and continued use of such technology.Aims: This study examines the determinants of user adoption of the PERSIS Solo mobile application through the application of the Unified Theory of Acceptance and Use of Technology 2 (UTAUT 2) framework. There are several influences of key factors examined in this study, they are performance expectancy, effort expectancy, social influence, facilitating conditions, hedonic motivation, price value, and habitual behavior on user acceptance, while taking into account the moderating role of demographic variables such as age, gender, and user experience.Methods: A quantitative approach was employed with 150 active users of the PERSIS Solo application as respondents. Data were examined using Structural Equation Modeling with Partial Least Squares (SEM-PLS) in SmartPLS to assess the validity and reliability of constructs as well as the relationships between variables.Results: Out of 25 tested hypotheses, six were supported. Social influence, hedonic motivation, and habit significantly influenced Behavioral Intention, while facilitating conditions, habit, and Behavioral Intention significantly affected Use Behavior.Conclusion: The study concludes that hedonic motivation and habit are dominant predictors of user acceptance and actual usage. The findings provide empirical insights for improving mobile applications in sports organizations and contribute to understanding digital fan-engagement systems in Indonesia.]]>
